Answer in brief
Define one user outcome and its data and permission dependencies, then prototype normal, denied, offline and error states with explicit behaviour and accessibility criteria for engineering.

- mobile app MVP UX UI process
Mobile app UX/UI — Bound the product outcome
The first release is bounded by one user outcome and the shortest credible route that demonstrates it.
Mobile app UX/UI — Map inputs and dependencies
Permissions, connectivity, account state, content and platform services sit beside the steps they can change.
Mobile app UX/UI — Draw the end-to-end flow
The flow includes real entry, decisions, returns, interruption and a stable completion signal.
Mobile app UX/UI — Prototype normal and failed states
Prototypes exercise loading, empty, denied, offline, error, success and recovery states with representative content.
Mobile app UX/UI — Specify the system rules
Screen specifications describe platform conventions, component behaviour, accessibility and content limits as testable rules.
Mobile app UX/UI — Test the engineering handoff
Engineering verifies source files, state coverage, interactions, assets and named acceptance scenarios before taking ownership.
Mobile app UX/UI — Record release learning
Release learning compares observed task outcomes with the intended result and records the next decision trigger.
Practical checklist
- Define one priority user outcome and the minimum sequence that proves it before expanding the feature list.
- Map permissions, interruption, offline behaviour, empty states, errors and recovery beside the happy path.
- Test navigation and task comprehension in a prototype before polishing the visual layer.
- Specify platform conventions, component behaviour, content limits and accessibility for every approved screen.
- Handoff includes source-of-truth files, state inventory, interaction notes, assets and named acceptance scenarios.
